Miller calls for momentum as South Africa spirit shows at T20 World Cup

Leading Group 2 with two wins and a no result against Zimbabwe, a win would lock in a semi-final spot, also knocking out their opponents.

"It's a must-win game for them, so they're going to be coming and charging, and we're definitely prepared for it."

"Pakistan are a great team, and they've got some serious match winners, but, we've just got to take it as it comes, and definitely the boys are up for it."

Miller made a crucial half-century in South Africa's win over India, only fuelling the flames of drama at the event, with five of the six teams in the group still mathematically alive for a semi-finals spot.

Looking towards his opponents' batting line-up, Miller wants his teammates to make early inroads with the ball, piling the pressure further on Muhammad Rizwan and Babar Azam to deliver at the top of the order.

"I think it is an area to exploit," he continued.

"This game is all about confidence, and yeah, they haven't probably performed the way they've wanted to, but they're world-class players, and we're expecting them to come out and bring their A-game and be up for the challenge.

"It's by all means not just going in there and expecting to get them out first ball or early up. We've got to work really hard for every wicket, and hopefully we can get them early and put the Pakistan middle order under pressure a little bit earlier than later."

South Africa remain the only undefeated team at the T20 World Cup, and the team from the outside look in good spirits while gunning for a long-awaited trophy at an ICC event.

Dale Steyn, who joined Alex Jordan on the Big Time Preview ahead of the match, is impressed by the body language and feels the group is in a mindset to make a tournament tilt.

"Just as a unit, when you see the South Africans on the field, they're all attacking. They're very aggressive.

"It just looks like there is a movement and a swagger in the team that I haven't seen for quite some time now, and it's good to see it back."

South Africa's T20I record since the last global tournament is strong, losing just five of their last 16 matches.

Miller credits the energy to consistency in the playing group, though individually, there is enough talent to always challenge.

"I think the continuity of the squad over time, guys have managed to sort of find their roles and sort of if one guy isn't doing well, another guy picks up the slack.

"The guys are really putting in the hard work. The tail-end, all-rounders as well, because going into competitions like this in one or two games we might need them. So yeah, we're definitely putting in the yards.

"I suppose we are finding lots of ways to win. We've done it over a period of time now. I'd say probably the last year, we've found ourselves in tricky situations and managed to get over the line."
